Abstract: A filling apparatus capable of using a single hydrogen storage container for as long as possible during hydrogen filling and maintaining opening degree of a flow rate adjusting valve within a predetermined range. A filling apparatus (100) includes a plurality of hydrogen storage containers (20: hydrogen cylinders or hydrogen storage tanks), a pipe (1) that connects a filling hose (8) and the hydrogen storage containers (20), a flow rate adjusting valve (3: flow control valve) interposed in the pipe (1), and a control unit (10), and the control unit (10) has functions of adjusting a threshold value for switching the hydrogen storage container (20) communicating with the filling hose (8) to another hydrogen storage container (20) and adjusting valve opening of the flow rate adjusting valve (3).

Abstract: A hydrogen filling apparatus that can quickly fill vehicles equipped with multiple large-capacity fuel tanks with hydrogen gas while complying with filling protocol. The hydrogen filling apparatus (100) of the present invention includes: a plurality of filling systems; a filling control device (10, 20) for each of the filling systems; a filling pipe communicating with a rear facility in each of the filling systems; a set of filling members (for example, flow control valves, flow meters) interposed in each of the filling pipes and connected to each of the filling control devices; and a filling hose connected to each of the filling pipes, each filling hose having a filling nozzle at a tip; wherein one of the plurality of filling control devices has a function of selectively exerting a first control mode that controls only the filling system including the filling control device and a second control mode shared as a control device for the plurality of filling systems, and a switching means for switching between the first control mode and the second control mode in the one of the filling control devices is provided.

Abstract: To provide a hydrogen filling system and a hydrogen filling method capable of preventing hydrogen from being filled at high filling rate in the same manner as the communication filling despite a condition that pressure, temperature and so on in the in-vehicle tank are not precisely grasped. The hydrogen filling system (100) of the present invention includes a control unit (CU1, CU2, CU3) for controlling hydrogen filling, wherein the control unit has a function of judging whether or not there is an abnormality in pressure or temperature data in an in-vehicle tank (IT) at communication filling and a function of stopping the communication filling and converting to non-communication filling when there is an abnormality in the pressure or the temperature data.

Abstract: A filling apparatus that does not significantly reduce a required pressure immediately after a start of hydrogen filling, and can reliably fill fuel cell vehicles and the like. The filling apparatus (100) includes a control unit (10), and the control unit (10) has a function of boosting pressure required from a hydrogen filling apparatus (100) to a rear facility (200) until initial pressure measurement is completed. The control unit (10) may have a function of determining whether or not communication filling is established, and when communication filling is established, setting a pressure higher than an internal pressure of a tank received from a vehicle side by a predetermined pressure (for example, 5 MPa) as a pressure required for the rear facility (200) at an initial stage of filling.
